SPRING BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 246,619, datedSeptember 6, 1881. i Application nien october 2o, leso. (No modei.)

To all whom it may concern:

Beit known that I, MELVIN N. LovELL, a citizen of the United States,residing at Erie, in the county ofErie and State otPennsylvania, haveinvented certain new and useful Improvements in Spring Bed-Bottoms; andI do hereby declare the following to be a full, clear, and

' exact description of the invention, such as will enable othersskilledin the art to which it appertains to make and use the saine,reference being had to the accompanying drawings, and to letters orgures of reference marked there on, which form a part of thisspecification.

This invention relates to the construction of spring bed-bottoms whichare so jointed that they may be rolled up and packed away in a smallcompass.

Heretofore in this class of bed-bottoms it has been common to place theslats upon short strips of sheet-iron connected together by the ordinarybutthinge; but 4this form has been found defective for the reason thatthe hinge is weak and the sheet metal apt 'to break when a heavy bodyhas been placed upon the bed, or when the device is rolled or handled.Anotherform of bed havingwedge-shaped blocks placed between the slatsand hinged thereto has been in common use, but this device is palpablyWeak, for the reason that the slats which are generally made of somelight wood will not hold the screws of said hinges for any length oftime, thus rendering the bed useless forthe purposes intended.

The object of my invention is to remedy these defects and produce across-stay that will be more strong and durable, and at the same timecom bine lightness and cheapness, and to this end the nature of myinvention consists in providing said cross-stays with clips havin pairof extensions formed on each end, and pintles for connecting each pairtogether, said pintles acting as bearing for the links, which connectthe clips together, and constitute with said clips the cross-stays.

It further consists of parts and combination of parts which willhereinafter be described.

My device is illustrated in the accompanying drawings, as follows:

Figure lrepresents aplan view of a fragment of a bed-bottom having myimproved construction, Fig. 2, an end view of the bed; Fig. 3, a likeView, showing the bed collapsed or contracted; Fig. 4,21. view the sameas Fig. 2, showing a slight variation; Fig. 5, a view ot the bed-bottomwhen rolled up, and Fig. 6, a view showing details ot' construction,which will more fully be explained hereinafter.

In the drawings, A A represent the longitudinal strips; B', the clips,which lie transversely to the strips A,and form, with thelinks B thecross-stay; C, the springs joined together by the links c.

The clips B' are provided with extensions e, arranged in pairs upon eachend, and support a pintle, which may be formed with or attached to theextensions e in any suitable manner. The upper part of these extensionsmay have their inner faces made square-shouldered, so as to form withthe top of the clip a socket for the slat to rest in.v By using thisconstruction the strips can be held in place by a single screw or rivet,a, in such a manner thatit v will not turn laterally.

Link B may be made of one piece, or, if preferred, it may be madein twopieces and jointed at b. It is obvious, by so forming thc link, thatthere will be no departure from the main object of my invention. Theobject in jointing this link is to decrease the width of the bed-bottom,4it' it be desired to use it upon a smaller-sized bed or asofa-bedstead.

The clip may be made of any suitable metal; but I prefer to usemalleable iron.

ThestripsA may be made of iron or wood, if desired, the clip beingchanged in size to suit the different widths.

To secure the bed when rolled, a hook, d, is provided on one end of thecross-stay, for the purpose of hookin g over thepivotpin b on the clipat the other end of the strip or stay.

1. In a spring bed-bottom, a series of clips forming part of thecross-stay, each clip having a pair of extensions at each end thereof,and pintles, substantially as described, to act as bearings for links,which connect the clips together, and constitute with saidv clips thecross-stay.

2. In a spring bed-bottom, a series of clips forming part of thecross-stay, each clip having extensions with square-shouldered insidefaces, forming a socket for the longitudinal slat and pintles, for thepurpose specied.

3. In a spring bed-bottom, a cross-stay hav- IOO ing clips provided witha pair of extensions at each end thereof, and pintles, substantially asdescribed, in combination with links for connecting said clips together,in the manner set forth.

4. In a spring bed-bottom, a cross-stay having clips provided with apair of extensions at each end thereof, and pintles, substantially asdescribed, in combination with jointed links for connecting said clipstogether, in the manner set forth.

5. In a spring bed-bottom, a. clip,.B', having extensions e and pintlesb, for the purpose specified.

6. In a spring-bed, a clip, B', having extensions e, provided with innersquare-shouldered
